Where To Find Census Tract Racial Datasets?

Hey,

I’ve been mapping out Potentially Underserved Communities in North Carolina over the past few weeks, and have a time-series animation from 2010-2023 at the Census Tract Level, but my professors are wanting me to go further back with the data. It seems like the first American Community Survey 5-Year Estimates came out in 2010, so I think I’ll have to use Decennial Census Data, but was having trouble locating anything prior to 2010 on there website. Any tips?
